What confuses me really is that I request a permission for _receiving_ a particular intent (whose action is boot_completed) - I do not define anywhere a permission the _broadcaster_ must request/hold
Thanks PS : testing vs asking - I found about the android.intent.action.QUICKBOOT_POWERON permission while browsing for an answer to this question - don't think I need it but added it :) On Monday, May 6, 2013 12:18:25 AM UTC+3, Piren wrote: > > I'm not 100% positive only the system can call it, but i'm pretty sure > about it.
